[0002] Flexible displays offer advantages such as bendability and rollability, enabling the design of new display devices. As one application of flexible displays, roll-up displays can provide screen display areas of different sizes according to user needs.

[0003] The limited sliding and unfolding space of a single-sided roll-up display device results in a smaller display area provided by the screen. Furthermore, its expandable area is located on one side of the fixed housing, and the display areas on the left and right sides of the fixed housing are asymmetrical, leading to poor viewing experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0010] In one embodiment of this disclosure, the telescopic bracket includes multiple telescopic units, which are arranged sequentially along the first direction. On the fixed housing and the same guide member, the first connecting portions and second connecting portions of different telescopic units are staggered along the first direction.

[0011] In one embodiment of this disclosure, the telescopic bracket further includes a limiting part, which is fixedly connected to the fixed housing and located near the first connecting part along the first direction.

[0013] In one embodiment of this disclosure, the sliding display device further includes a synchronous mechanism, the driving end of which cooperates with the first sliding member to drive the telescopic bracket to unfold or retract along the extension direction of the guide rail.

[0014] In one embodiment of this disclosure, the co-movement mechanism includes a gear set, a first rack, and a second rack.

The telescopic brackets are disposed on both sides of the fixed housing along a second direction and are slidably connected to the guide rails. A flexible display module is wound around the telescopic brackets. When the telescopic brackets on both sides of the fixed housing unfold along the extension direction of the guide rails, they can push both sides of the flexible display module to unfold along both sides of the fixed housing, thereby increasing the display area of ​​the flexible display module.

Detailed Implementation

[0037] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0038] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0039] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0040] Currently, most rollable displays use a single-sided roll-up design, which limits the sliding and unfolding space of the flexible display module, resulting in a smaller display area. When rollable displays are used in laptops, the expandable area of ​​the screen is located on one side of the fixed casing, causing asymmetry in the display area on both sides of the fixed casing and poor viewing experience.

[0041] Based on this, the present disclosure provides a scrolling display device. For example... Figures 1 to 13 As shown, the sliding display device includes a fixed structure 1, a telescopic bracket 2, and a flexible display module 4. The fixed structure 1 includes a fixed housing 11 and a guide rail 12. The guide rail 12 is disposed on opposite sides of the fixed housing 11 along a first direction. The telescopic bracket 2 is disposed on opposite sides of the fixed housing 11 along a second direction. The telescopic bracket 2 is slidably connected to the guide rail 12. The second direction is perpendicular to the first direction. The flexible display module 4 is fixedly connected to the first surface of the fixed housing 11, extends away from the fixed housing 11 along the second direction, and is wound around the second surface of the fixed housing 11 opposite to the first surface along a third direction. The third direction is perpendicular to the first and second directions.

[0042] Telescopic brackets 2 are provided on both sides of the fixed housing 11, and the flexible display module 4 is wound around the telescopic brackets 2. When the telescopic brackets 2 are extended along the extension direction of the guide rail 12, they can push both sides of the flexible display module to unfold along both sides of the fixed housing 11, thereby increasing the display area of ​​the flexible display module 4. Therefore, this sliding display device can improve the sliding and unfolding space of the flexible display module 4, increase more sliding freedom, thereby expanding the display area of ​​the flexible display module 4, and can control the symmetry of the display area on both sides of the fixed housing 11, resulting in better viewing.

[0043] It should be noted that the first direction is Figure 1 The y-direction is shown in the figure, and the second direction is... Figure 1 The x-direction is shown in the figure, and the second direction is... Figure 1 The z-direction is shown in the figure. The first direction is the length extension direction of the telescopic bracket 2, the second direction is the length extension direction of the guide rail 12, and the third direction is the thickness direction of the fixed housing 11.

[0044] like Figures 1 to 6 As shown, the sliding display device includes a fixing structure 1, which includes a fixing housing 11 and two guide rails 12. The fixing housing 11 is flat and has two first sides and two second sides. The two first sides are spaced apart along a first direction, and the two second sides are spaced apart along a second direction. The first sides and the second sides are perpendicular to each other. The two guide rails 12 are respectively located on the two first sides of the fixing housing 11. The guide rails 12 are strip-shaped and extend along the second direction, protruding from the fixing housing 11.

[0045] The telescopic bracket 2 includes a first sliding member 21, a second sliding member 22, and a guide member 23. The first sliding member 21 and the second sliding member 22 are slidably connected to two guide rails 12, respectively. The guide member 23 extends along a first direction and is fixed between the first sliding member 21 and the second sliding member 22. The guide member 23 connects the first sliding member 21 and the second sliding member 22 so that when one of the first sliding member 21 and the second sliding member 22 is subjected to force, the other can move accordingly. For example, the guide rails 12 can be configured as hollow columns, and the first sliding member 21 and the second sliding member 22 can be configured as rods, with the first sliding member 21 and the second sliding member 22 slidably connected within the guide rails 12.

[0046] To ensure that the telescopic bracket 2 consistently provides support for the flexible display module during the deployment of the sliding display device, the telescopic bracket 2 includes at least one telescopic unit 24. Each telescopic unit 24 may include a connector 241, one end of which is hinged to the fixed housing and the other end slidably connected to the guide member 23; alternatively, one end of the connector 241 may be slidably connected to the fixed housing and the other end hinged to the guide member 23. However, the support provided by a single connector 241 is quite limited, therefore, it is necessary to improve the telescopic bracket 2.

[0047] In this embodiment, the telescopic bracket 2 includes multiple guide members 23, which are arranged sequentially along the second direction. The guide member 23 farthest from the fixed housing 11 is fixedly connected to the first sliding member 21 and the second sliding member 22. The remaining guide members 23 can be slidably connected to the first sliding member 21. The telescopic unit 24 includes multiple connectors 241, which are respectively connected between the fixed housing and the guide members 23, and between two adjacent guide members 23.

[0048] The supporting surface of the telescopic bracket 2 is flush with the first surface of the fixed housing 11 to prevent a discontinuity between the telescopic bracket 2 and the fixed housing 11 in the third direction, which could cause mold marks on the flexible display module. It can be understood that the supporting surface is the side of the telescopic bracket 2 closest to the first surface of the fixed housing 11 along the third direction. Along the third direction, the two mutually distant sides of the connector 241 are flush with the two mutually distant sides of the guide 23, respectively, to prevent a discontinuity between the connector 241 and the guide 23 from affecting the support performance of the flexible display module and causing screen mold marks. It should be noted that the third direction is perpendicular to the first and second directions, and the third direction is the thickness direction of the fixed structure 1.

[0049] When the first sliding member 21 slides relative to the guide rail 12, the distance between the guide member 23 furthest from the fixed housing 11 and the fixed housing 11 increases. This causes the connecting member 241 to rotate while sliding along the fixed housing 11 and the guide member 23, thereby causing the remaining guide members 23 to move in the second direction, thus realizing the unfolding of the telescopic bracket 2. It should be noted that during the unfolding or retraction of the telescopic bracket 2, the included angle between the connecting member 241 and the fixed housing 11 and the guide member 23 is never equal to 90 degrees.

[0050] The second sliding member 22 can be set as a single piece, and the guide member 23 can be slidably connected to the second sliding member 22. However, to prevent the guide member 23 from jamming due to inconsistent sliding distances at both ends, which would affect the deployment of the telescopic bracket 2, the second sliding member 22 can be set as multiple sliding segments 221 that are slidably connected to each other. The guide members 23, except for the one farthest from the fixed housing 11, are fixedly connected to the multiple sliding segments 221 respectively. The sliding between the guide member 23 and the second sliding member 22 is converted into sliding between multiple sliding segments 221, which significantly improves the reliability of the telescopic bracket 2. In this embodiment, the second sliding member 22 includes a first segment and a second segment. The first segment is slidably connected to one end of the guide rail 12 along a second direction, and the second segment is slidably connected to the first segment.

[0051] The telescopic unit 24 also includes a first connecting portion 242 and a second connecting portion 243. The first connecting portion 242 and the second connecting portion 243 are staggered along a second direction on the fixed housing and different guide members 23. The two ends of the connecting member 241 are respectively connected to the first connecting portion 242 and the second connecting portion 243. The first connecting portion 242 is slidably connected to the guide member 23, and the second connecting portion 243 is fixedly connected to the guide member 23. The first connecting portion 242 can slide back and forth relative to the guide member 23, and the second connecting portion 243 is fixed to the guide member 23, serving as a connection and limiting function.

[0052] To better support the flexible display module, the telescopic bracket 2 includes multiple telescopic units 24, which are arranged sequentially along a first direction. Different telescopic units 24 support different parts of the flexible display module. The first connecting portions 242 and second connecting portions 243 of different telescopic units 24 on the fixed housing and the same guide member 23 are staggered along the first direction, ensuring that the guide member 23, connecting member 241, and first connecting portion 242 all have a certain degree of synchronous movement when the telescopic bracket 2 is deployed, thus maintaining an equal distance between adjacent guide members 23.

[0053] The telescopic bracket 2 also includes a limiting part 25, which is fixedly connected to the fixed housing and located near the first connecting part 242 along the first direction. Specifically, the limiting part 25 can be located between the first connecting part 242 and the second connecting part 243 of two adjacent telescopic units 24, or it can be located between the guide rail 12 and the first connecting part 242 along the first direction. The limiting part 25 and the second connecting part 243 together define the sliding stroke of the first connecting part 242, preventing the deployable telescopic bracket 2 from over-expanding and causing damage to the flexible display module. It should be noted that the limiting part 25 can also be fixed between the first connecting part 242 and the second connecting part 243 on the guide member 23.

[0054] Multiple telescopic units 24 are divided into at least one pair of telescopic unit groups 240. Each pair of telescopic unit groups 240 includes two telescopic unit groups 240, which are symmetrically arranged about a second direction. Each telescopic unit group 240 includes at least two telescopic units 24, and the distance between any two adjacent telescopic units 24 in different telescopic unit groups 240 is equal in the second direction. The support areas of different telescopic units 24 in the two telescopic unit groups 240 are equal, and the support areas of the two telescopic unit groups 240 are symmetrical about the centerline of the flexible display module along the second direction.

[0055] like Figure 7 As shown, the sliding display device also includes a synchronizing mechanism 3. The synchronizing mechanism is located within the guide rail 12. The synchronizing mechanism 3 may include a gear set 33, a first rack 31, and a second rack 32. The first rack 31 and the second rack 32 are respectively located at the ends of the two first sliding members 21 that are close to each other. The second rack 32 is offset from the first rack 31 in a first direction. The gear set 33 meshes between the first rack 31 and the second rack 32. A motor can drive one gear in the gear set 33, which in turn drives the other gears to rotate. This causes the first rack 31 and the second rack 32, which are engaged with the gear set 33, to move away from each other. The first rack 31 and the second rack 32 then drive the two first sliding members 21 connected to them to move away from each other, so that the telescopic brackets 2 on both sides of the fixed structure 1 unfold synchronously along the extension direction of the guide rail 12.

[0056] In this embodiment, the gear set 33 includes two first gears 331 and at least one second gear 332. One of the first gears 331 meshes with a first rack, the other first gear 331 meshes with a second rack, and the second gear 332 meshes between the two first gears 331. This arrangement can reduce the wear of each gear in the gear set 33 and improve the fatigue life of the gear set 33.

[0057] When the first sliding member 21 moves to the left along the second direction, the first rack 31 engages with a first gear 331, causing the first gear 331 to rotate counterclockwise. The first gear 331 engages with a second gear 332, causing the second gear 332 to rotate clockwise. The second gear 332 engages with another first gear 331, causing the other first gear 331 to rotate counterclockwise. This, in turn, engages the second rack 32, causing the rack to move to the right along the second direction, thus moving the other first sliding member 21 to the right. This achieves synchronous extension of the two first sliding members 21, allowing the telescopic brackets 2 on both sides of the fixed housing 11 to deploy synchronously. It should be noted that the first rack 31 or the second rack 32 only contacts one of the two first gears 331, and does not contact the other.

[0058] It should be noted that the synchronous mechanism 3 is not limited to the structure shown in the figure. It can also use a push rod connected to the first sliding member 21, which extends to drive the two first sliding members 21 to move away from or towards each other. Alternatively, it can use a lead screw connected to the first sliding member 21, with the rotation of the nut causing the two first sliding members 21 to move away from or towards each other. Other possible methods can also be used to implement the synchronous mechanism 3, which will not be elaborated here.

[0059] Figures 8 to 10 This is a schematic diagram illustrating the deployment process of the telescopic support 2. Wherein, Figure 8 With the telescopic bracket 2 in its retracted state, the guide member 23 is in contact with the connector and the fixed housing 11. The distance between two adjacent guide members 23 is equal to the dimension of the connector along the second direction. The distance between the first connecting part 242 and the second connecting part 243, which are connected to the same connector, is the largest along the first direction, and is approximately equal to the dimension of the connector along the first direction.

[0060] Figure 9 With the telescopic bracket 2 in its unfolded state, the first and second sliding members on both sides of the fixed housing 11 simultaneously slide out from the guide rail 12. The two first sliding members move away from each other relative to the guide rail along a second direction, and the two second sliding members also move away from each other relative to the guide rail along a second direction. The distance between the guide member 23, which is furthest from the fixed housing 11, and the fixed housing 11 increases, causing one end of the connecting member 241 of each telescopic unit to rotate and the other end to slide, thus gradually unfolding the telescopic bracket 2 on both sides of the fixed housing 11.

[0061] The first connecting part 242 and the second connecting part 243 are placed in a staggered manner. As the distance between the guide members 23 gradually increases, the included angles A, B, C, D, E, and F between different connecting members 241 and guide members 23 are equal, making the distances L1, L2, L3, and L4 between adjacent first guide members 23 equal. This ensures that when the telescopic bracket 2 is deployed, the guide members 23, connecting members 241, and the first connecting part 242 all have a certain degree of motion synchronization.

[0062] Figure 10 When the telescopic bracket 2 is fully extended, the support areas 26 of different support units are of equal size, and the support areas 26 of two support units are symmetrical about the center line of the flexible display module 4 along the second direction with respect to the support areas 26 of the other two support units.

[0063] like Figure 11 As shown, the flexible display module 4 can be covered by the frame 5 of the sliding display device, that is, the frame 5 of the sliding display device limits the sliding trajectory of the flexible display module 4, and the flexible display module 4 can slide relative to the frame 5. The flexible display module 4 is bonded to the first surface of the fixed housing 11 to prevent relative movement between the flexible display module 4 and the fixed housing 11 during the unfolding of the telescopic bracket 2.

[0064] like Figure 12 As shown, an elastic tensioning part 6 can be provided at the tail end of the flexible display module 4 for tensioning. For example, the elastic tensioning part 6 can be a spring or a PI bar. During the rolling process, the elastic tensioning part 6 remains in a tensioned state, which can reduce the bulging phenomenon of the flexible display module 4 and promote the rolling movement of the flexible display module 4.

[0065] Figure 13 This is a front view of the flexible display module 4 in its retracted state. The display area 41 of the flexible display module 4 is divided into a fixed area 411 and non-fixed areas 412 located on both sides of the fixed area 411. The flexible display module 4 is currently in its retracted state. It can be understood that the fixed housing 11 fixes and supports the fixed area 411 of the display area 41, and the telescopic brackets 2 on both sides of the fixed housing 11 support the non-fixed areas 412 of the display area 41, thereby ensuring that the display area 41 of the flexible display module 4 is in the same plane. The non-display areas 41 of the display module are bent along the edge of the telescopic brackets 2 and fixed in the opposite direction to the second surface of the fixed housing 11.

[0066] Figure 14 This is a schematic diagram of the sliding display device when it is fully extended. As the telescopic bracket 2 unfolds, the area of ​​the non-fixed area 412 of the display area 41 gradually increases, thereby increasing the display area of ​​the sliding display device. The increased portion of the non-fixed area 412 consists of a first sub-area 4121 and a second sub-area 4122, with the areas of the first sub-area 4121 and the second sub-area 4122 being equal. The total display area of ​​the display area 41 of the flexible display module 4 is twice that of the sliding display device in its retracted state. Therefore, this sliding display device both expands the area of ​​the display area 41 and maintains the left-right symmetry of the display area 41.

[0067] like Figures 1 to 4As shown, this disclosure provides an electronic device. The electronic device includes the sliding display device 100 described in any of the above embodiments of this disclosure. The specific structure and beneficial effects of this electronic device can be referenced from the sliding display device 100, and will not be repeated here.

[0068] Electronic devices can be traditional electronic devices, such as mobile phones, computers, televisions, and video recorders, or emerging wearable devices, such as virtual reality devices and augmented reality devices, which will not be listed here.

[0069] It should be noted that, in addition to the scrolling display device 100, the electronic device also includes other necessary components and parts. Taking a laptop as an example, the electronic device may also include a host 200, and the fixing structure 1 of the scrolling display device 100 is rotatably connected to the host 200.

[0070] A keyboard for input can be set on the host unit, and a camera for imaging can be set in the display area of ​​the flexible display module. Those skilled in the art can make corresponding additions according to the specific usage requirements of this electronic device, which will not be elaborated here.
